The online test is a displacement-control test for the simulation of earthquake responses of structural systems. The test is made difficult when the tested structure becomes stiff because of difficulties in displacement-control. This paper presents dispplacement-force mixed-control algorithms in which the test is force-controlled when the test structure is stiff, thereby making it possible to carry out online test to stiff systems. Two types of mixed-control, one named "displacement-force combined control," and the other "displacement-force switching control," is proposed. In the combined control, one jack is displacement-controlled for loading the flexible part, while the other jack is force-controlled for loading the stiff part. In the switching-control, one jack is force-controlled when the test structure is stiff but switched to displacement-control once the structure is made flexible. Effectiveness of the mixed-control procedures is demonstrated by online tests applied to a base-isolated building structure.
